| 应用 | Western Blot(0.1 µg/mL) |
| 目标/特异性 | Detects mouse BAFF/BLyS/TNFSF13B in direct ELISAs and Western blots. In direct ELISAs, approximately 30% cross-reactivity with recombinant human (rh) BAFF, 10% cross-reactivity with recombinant mouse (rm) LIGHT, rhEDA‑A2, and rhTRANCE and less than 1% cross‑reactivity with rmTWEAK, rhAPRIL, rmFas Ligand, rhGITR Ligand, rmOX40 Ligand, rmTNF‑ alpha, rmTRAIL, and rm4‑1BB Ligand is observed. |
| 使用方法 | Western Blot: 0.1 µg/mL Neutralization: Measured by its ability to neutralize BAFF/BLyS/TNFSF13B-induced proliferation in mouse B cells. The Neutralization Dose (ND50) is typically 0.01-0.04 µg/mL in the presence of 3 ng/mL Recombinant Mouse BAFF/BLyS/TNFSF13B and 10 µg/mL Goat F(ab)2 Anti-mouse IgM. |

| 背景 | BAFF (also known as TALL-1, BLyS, THANK) is a type II transmembrane glycoprotein belonging to the TNF superfamily and has been designated as TNF superfamily member 13B (TNFSF13B). Mouse BAFF is a 309 aa protein consisting of a 248 amino acid (aa) extracellular domain, a 21 aa transmembrane region and a 45 aa cytoplasmic tail (1, 2). BAFF has the typical structural characteristics of the TNF superfamily ligands. It is a homotrimeric protein having the structurally conserved motif known as TNF homology domain (3, 4). A higher ordered structure composed of a cluster of trimeric units resembling the structure of a viral capsid has also been reported (4). Mouse BAFF may be shed from the cell surface by proteolytic cleavage between R126 and Ala 127 to yield a soluble form of the protein detectable in serum (1, 5). Within the TNF superfamily BAFF shares the highest homology (48%) with APRIL (1). BAFF shares with APRIL the ability to bind to BCMA and TACI and also binds specifically to BAFF receptor (BAFF R, also known as BR3 or TNFSFR13C), which is the principal BAFF receptor (6-8). All three receptors are type III transmembrane proteins that are expressed in B cells. BAFF and APRIL can form active heteromers that bind TACI (9). BAFF is expressed in peripheral blood mononuclear cells, in spleen and lymph nodes. Its expression in resting monocytes is upregulated by IFN-alpha, IFN-beta, LPS and IL-10. BAFF provides critical survival signals to a subset of B cells with intermediate maturation status (T2 B cells) during the immune response (10). BAFF also plays an important role in the development of lymphoid tissue and enhances the survival of activated memory B cells (7, 11). Human and mouse BAFF share 86% aa sequence identity (1). |

Cell Proliferation Induced by BAFF/BLyS/TNFSF13B and Neutralization by Mouse BAFF/BLyS/TNFSF13B Antibody. In the presence of Goat F(ab)2 Anti-mouse IgM, Recombinant Mouse BAFF/BLyS/ TNFSF13B (Catalog # 2106-BF) stimulates proliferation in mouse B cells in a dose-dependent manner (orange line). Under these conditions, proliferation elicited by Recombinant Mouse BAFF/BLyS/TNFSF13B (3 ng/mL) is neutralized (green line) by increasing concentrations of Mouse BAFF/BLyS/TNFSF13B Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2106). The ND50 is typically 0.01‑0.04 µg/mL. |
